I think it’s likely that limited connectivity between FF “nodes” would suffice for maintenance scheduling. A “free” (uncommitted) node positioned between several operating ones could pick up the load while each was being serviced in staggered sequence. It could also serve as an emergency backup or overload resource. This would amount to a flexible “local” or regional grid, of course. There is a wide range of possible configurations which would be used depending on the population density, etc. I would expect a self-powered manufacturing plant, e.g., would have its own “maintenance and overload” sub-node to permit rotating servicing as convenient.
